The use of controlled frequency vibration (CFV) technology and its applications in construction continue to grow - *Paul Jaworski Controlled frequency vibration (CFV) technology has been around since the mid-1990s for concrete pavement applications. The technology has seen a gradual increase in acceptance, particularly in certain applications. For the 0-37mm (1.5”) slump pavement mix designs, many contractors were experiencing material separation due to speeds over 8,000vibrations/minute (VPM). With the wi

The use of controlled frequency vibration for concrete continues to grow, writes Paul Jaworski Controlled frequency vibration (CFV) technology has been around since the mid-1990s for concrete pavement applications. The technology has seen a gradual increase in acceptance, particularly in certain applications. For the 0- to 37mm (1.5”) slump pavement mix designs, many contractors were experiencing material separation due to speeds over 8,000vibrations/minute (VPM). With the wide variability of concrete

Resurfacing of an important port road connection in Nigeria is now complete. The Apapa Wharf road provides a vital link to the busy port of Apapa, close to Nigeria’s commercial centre of Lagos in the south west of the country. The road has been in desperate need of repair as it had been badly worn due to heavy traffic volumes. The new road section has now been constructed from concrete in a bid to offer a long working life and to allow the route to cope better with the high percentage of heavily laden truck

SunWest Construction Development Corporation has been using a concrete paver from Power Pavers at the new Bicol International Airport in the Philippines. The machine has been used to pave a runway, taxiways, and aprons for the US$105 million project underway in the Daraga municipality of Albay province in the Bicol Region. The new facility has been built as a replacement to the single runway Legazpi airport, which is located in an urban area where future expansion is not possible. SunWest used its Powe

Sinaloa State in Mexico is to benefit from major infrastructure development, with the budget being supplied by the Mexican Government. One of the key road links that will be upgraded as a result of the US$462 million budget is the link between Badiraguato and Parral, which runs through the Sierra Madre Occidental mountain range. Highway 24 will be upgraded, improving safety for drivers along this section, which features numerous sharp turns and steep gradients at present. A central section of this highway

Paving machines from Dynapac were used recently to install roller-compacted concrete (RCC) in Germany. The job was carried out in cooperation with the firm’s long-term customer STRA-LA-BAU, based in Dortmund, Germany. The German contractor STRA-LA-BAU has several Dynapac pavers in its fleet, including DF45CS, F1200CS and F1700C models, as well as Dynapac rollers. The firm laid the RCC surface on behalf of Holcim. There is an external warehouse planned on which heavy machine parts for the packaging indust
